Atmos develops cold-drip coffee maker with MIM parts

Atmos Coffee, Sydney, Australia, is seeking crowdfunding via an Indiegogo campaign for a new cold-drip coffee maker which uses MIM parts. The Atmos coffee maker is produced from a combination of MIM and investment cast 316 stainless steel and borosilicate glass, making it both strong and food safe.

The Atmos is comprised of two bottles, one to hold the water which drips over the coffee via an atmospheric valve, and one for collecting the drip. When assembled, the Atmos ‘body’, comprising a steel basket filled with ground coffee, an integrated filter and an air lock, sits between the two bottles.

The coffee maker brews cold-drip coffee using atmospheric pressure. When the basket is filled with coffee grounds and the upper bottle with cold water, the water filters through the basket into the collection bottle. The coffee then flows along the grooves on the underside of the basket using surface tension, collecting in the glass bottle below, where it can be stored fresh for five days.

By simplifying the design to eliminate pipes, funnels and other small parts. Atmos’s designers state that they have produced a café-grade coffee maker which is both simpler to use and easier to clean than other coffee makers. The company states that, “the seamless, precise and integrated design of Atmos is achieved through a cutting-edge process known as Metal Injection Moulding, combined with Investment Casting.”

Following manufacture, the metal components are laser welded and hand polished. Along with working prototypes, the Atmos team has reportedly sourced all suppliers and manufacturers ready for production in February 2018.
